' 7 claims. l(or. 137-93) This invention relates to certain new-and useful improvements in ilu-sh valves. Y i

The primary obj ect ofthe inventionv is'V to -provide a ush valve. especially designed for-use 5; connection with waterclosets-wherein-theusual flush tank isVv eliminated andthe control ofi-'the flow ofv water froma-service--pi'pe to the-bowlK of the water closet is accomplished" by the-'interepositioning of the ush valve-between the-water- 1@ service pipe and water closet bowl. -A further object ofthe invention is: to provide a flush valve of the-foregoing character where-- in the valve embodies-a -casi-ng having a parti-tion' therein between-the water supply inletv tothe cas-- '15:' ing and the-valve controlled outlet from-the-cas-fing to reduce pressure on the valve and eliminate?- hammering action thereof for the -moreeffective.v

operation of the-valve. n A still further object of the inventionis to Sprovide aA flush valve: for water 'closets set into` a Water service. pipe and operating in the absence of theV usual flush tank with a oat memlzxer-con nected to Athe vValve-,within c a casing-y and 1 seating4 in a cup. member having a.- restricted outlet teef-- '25; feet easy and slow closing movement of the valve'- on its seat..

, Referring more indetail to theaccompan-ying drawing, there is illustrated a flush valve for waterclosets operating in the absencefof 'theusual ilush tank and controlling directcommunica- :50. tion between a water service pipe and the bowl of the water closet, the -flush val-vecomprising a casing 10 hav-ing'the open -exteriorly'threaded upper end thereof closed by-a screw cover 11, movement of which is facilitated bythe integral t5v polygonal nut projection 12.rising centrally from tapered to provide avalve-seat and said casingbelow the-tapered end- 13 extendsdownwardly in 6E'- cylindrical formationas shown atl--provifsl-ing4 a chamber lbelow-the valve-seat'- 14 vfor-housing a part of the valveoperati-ng---mechanisrr-i: The lower end` ofv the cylindricalportier-r15` of the casing-is. externally threadedasrat 1'7 toffacili- 6531 tate attachment toan L or other part" ofA thel waterv closetV for directing-water-intothe water closet bowl. n

A nipple Meis-carried bythe upper end-"01- vthe casing lofor-attachment-tofa-Water service pipe 705;. and to reduce the rushof water through theopening in the valve seat 14, there is provided a baffle-'01e partition-within the casing-between the-water' inlet nipple 18 andthe val-ve seat 141, The partitionor-watery haine-194s lthe 7M- form of a plate shaped -tothave its edges Contact the-sidewalls of the-casinglo and-itstapered- 1`ower end-13g thebale-plate-IS-bei-ng retained"v in position- `by 'guidelugsf--20'- carried by' the rimierface ofthe-casing 10 yadjacent its-upper-end-whil'e 80.--

kthe lower end ofthe-'baule plate-lQ-'is curved 'as engaged with the -ri-b 22 projecting upwardly 85.15,v

fromthe-lower tapered-end 1301i the casi-ng l0;l The lower curved-end 211 of the baiile--pllalw'el-19` isv provided with-anopening 23 that isf'of a-diametergreater than the diameter ofthe wateif passage through the-nipple 18- so that` the owl 96;? of Water through the-casing 10 willfhave the pressure-reduced when passing. through the valve opening 14 as comparedwith the velocity when iiowing-throughv-the-inlet nipple 18; Thefbaie plate 19 divides the-casing 10 into two-spaced 951; chambers 24 and 25.v and a part ofthe valvemechanism is disposedfwithin the chamber 25:

As shown in Figurev 1, the'side ofk thebailleplate l9- facing the chamberl 25 carries ybowl or cup-shaped-member-26 open at its upper side 100 and having'a depending'bearing 27 for-a valve stem 28, the bearing Z'T'being further bracedby thebraeketarm 29 extending from the'bafe plate 19 beneathk the cup-shaped member 26.r The valve-disk 30 is detachably engaged with the 105- lowerend ofthe valve stem 28 and a ball'float 31 is removablyv engaged-1 ywith the `upper' endv of the valve stem landwhen-the valve disk 30' is engaged with its seat 14, the ball float 31 is seated in the cup-shaped memberA 26. For pur- 1W 2.x poses presently to appear, the lower side of the cup-shaped member 26 adjacent to and laterally oi the stem bearing 27 is provided with a small opening 32, preferably one-sixteenth inch in diameter.

The operating means for the valve 30 is associated with the lower cylindrical end l oi' the valve casing le, the cylindrical end carry ing a `horizontal ouwardly directed bearing boss 33 through which the rod 34k or a part ofthe valve' operating mechanism extends to enter the chamber 15 and packed in the bearing boss' as at 35 to prevent water leakage. The vouter end of the bearing boss 33 is provided with a V- shaped socket formed by tapering opposed walls 36 shown more clearly in Figurev 3, the bearing boss having an axial opening 37tnerein iortnc mounting oi the rod 34. AThe outer end of the rod 34 carries an enlarged cylindrical headSi having opposite sides thereof adjacent'the rod 3 4 tapered as at 39 to be receivedin the V-shaped ysocket,in the outer endv of the bearingaboss Astransverse threaded openingAO is provided in the head 38 to receive the shank 41 of the operating handle` 42. A casing cap 43 is threaded onto the bearing-boss V33 4as shown in `Figure l, with the closed outer en d thereof spaced from .thevhead 33 'and carryingan ,external cushion block 44 forming a rest for the seat cover ofV a wateijcloset, aside wall ofthe casingrcap 43 having` an opening 45 therein for-passage of the, shank oi .the operatinghandle 42.` A coil spring 46 is interposed between the outer closed,A end of the casing cap 43 and the outer-end of the rod head 3S for normally seating the tapered sidesl 390i the head 38. in the MV-shaped socket in the bearing boss 33. v Y

`The inner end o ,therod34 that projects into, thevchamber 16 has one end of an `angle arm 47 secured thereto asat 48, the other endof the angle arm 47 being loosely engaged as at 47a with the lower end of the Valve operating -rod 49 extending upwardly througha guide ring `50 carriedy centrally of aV transverse spider arml and terminating adjacent the lower face of the valve disk 30. ,Y

Inthe operation of thefiush valve-the handle 42is shifted to impart rotary and axial movement oi the vrodfi for moving the tapered end 39 of the head 38 'out ofthe V-shaped socket in the outer end of the bearingbess 33 against the tension of the spring 46, rotary movement oi therod 34 and angle arm 47, raising the valve operating rod 49 to unseat the diskvalve 30 from its seat 14, the

ball float'31 rising upwardly of vits cup-shaped seat,

26with thefwater flowing through the valve opening and chamber 16 toenter the bowl of the water closet. K- Thel springr46 immediatelynreturns the head 38t and rod 34 to the position shown in Fig# ure 1 with; the valve operatingrod 49 lowered out oi the descending path o movement of the valve disk 30, the valve disk closing by its weight on the seal 14 and against the buoyancy of the ball noat 31 lowering towards its seatand retarded in such movement by the ball iloatacting upon the `Water in the cup-shaped member 26, the water inthe cup-shaped member slowing" discharging through the opening 32 inthe bottom thereof under connnement of the ball float. The valve disk 3i) is normally retained on its seat by water pressure in the casinglO, aided by they veight ofthe vvalve and stem c arryingthe same, the ball float 31 aiding in the unseating of the valve in the presence of an yini-rush of water and flow through the valvecasing whilethe closing movement of the valveV disk upon its seat 14 is retarded as stated by the ball float 31 entering the cup-shaped member 26 and the slow discharge of water through the opening 32.

While there is herein shown and described the preferred embodiment of the invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.
